Rome is 4 hours ahead of Brasília
Best overlap: 8:00 AM to 2:00 PM in Brasília is 12:00 PM to 6:00 PM in Rome.
The overlap falls at 8:00 AM to 2:00 PM in Brasília, or 12:00 PM to 6:00 PM if you're in Rome. Even with Rome ahead by 4 hours, your workdays overlap by a comfortable 6 hours — plenty of flexibility for both sides. Heads up: because Rome changes its clocks and Brasília doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
